6. 6 True preservation is needed Deterioration of the storage medium Obsolescence of the storage medium Obsolescence of the data format Obsolescence of the software Obsolescence of the hardware required to run the software “ The goal of digital preservation is the accurate rendering of authenticated digital content over time. ” (ALA)

7. 7 ExLibris Rosetta Version 1.0 released January 2009 New digital library software package Based on preservation needs Takes repository solutions one step further

8. 8 based on an article by Pricella Caplan (Premis) What makes it „preservation“?

9. 9 Availability (capture/selection) Definition: It is truism that you can not preserve digital objects that you do not control. What is supported in Rosetta: Deposit module Software Development Kit Submission applications Availability Identity Understandability Fixity Viability Renderability Authenticity

10. 10 Identity (description) Definition: The digital object must be described in sufficient detail to allow future access and/or use. What is supported in Rosetta: Supporting persistent identifiers (internal and external) Storing descriptive information on the AIP: Using the out of the box DC editor Integrating with descriptive tools Availability Identity Understandability Fixity Viability Renderability Authenticity

11. 11 Understandability (documentation) Definition: The repository is responsible for providing and preserving enough information to ensure future users to understand the preserved objects. What is supported in Rosetta: Rosetta stores descriptive and preservation metadata The data model is based on a standard model - PREMIS (IE, Rep, File) and METS file. The elements are standard - Rosetta supports the PREMIS elements as preservation metadata Availability Identity Understandability Fixity Viability Renderability Authenticity

12. 12 Fixity (secure storage) Definition: Protect digital objects from unauthorized changes, whether deliberate or in-deliberate. What is supported in Rosetta: On going fixity checks Fixity stored for both the metadata and the files. Support for a write once policy – any change is a new version. Fixity validation upon receiving. Availability Identity Understandability Fixity Viability Renderability Authenticity

13. 13 Viability (media management) Definition: Viability is the quality of being readable from media. What is supported in Rosetta: Ongoing fixity and virus checks on the files stored on the permanent repository. Abstraction of the application and the storage layer. All information stored on disk, which is proven technology. Availability Identity Understandability Fixity Viability Renderability Authenticity

14. 14 Renderablity (format strategy) Definition: Ensuring that a digital file is renderable (displayable, playable…) may be the heart of the digital preservation process. What is supported in Rosetta: Characterization. Preservation planning module. Support for different preservation strategies. Availability Identity Understandability Fixity Viability Renderability Authenticity

15. 15 Authenticity (authentication) Definition: Authenticity means that the integrity of both the source and the content of the object can be verified. What is supported in Rosetta: Producer management. Auditing. Human assessment is possible. Write once repository. Availability Identity Understandability Fixity Viability Renderability Authenticity
